ABSTRACT
The membrane is one of the key inner parts lithium-ion batteries, which determines interfacial structure and internal resistance, ultimately affecting capacity, cycling, safety performance cell. In this article, an alginate-based fiber composite was successfully fabricated from cellulose calcium alginate with flame-retardant properties via a traditional papermaking process. membrane, plays bridging role acts as filler. After 100 cycles, batteries by separator exhibited better capacity retention ratios (approximately 90%) compared those commercial PP separators. Furthermore, demonstrated fine thermal stability electrochemical properties, showing stable charge-discharge capability no hot melt shrinkage at higher temperatures, breakthrough in improving This research affords new way for large-scale fabrication safe battery
